    What this page is

    This is generated FPF reference text from the specification preface or supporting sections. It helps interpret FPF; it is not FPF Reference product documentation.

    Methodology

    Use it to understand how the specification wants to be read, then return to a route, pattern, or work packet for active work. Cite generated IDs only when the wording changes the task decision.

    Content

    When the line is ready, it should be possible to rewrite it into one of these minimal forms.

    Shared-space form

    SourceSetFamily      = ...
SourceSetRef?       = ...
SearchSpaceRef         = DeclaredCharacteristicSpace@...
OutcomeSpaceRef        = DeclaredCharacteristicSpace@...
SpaceRefRelationKind   = sameDeclaredSpaceAs
SourceToOutcomeRelation= <direction, mode, carrier>
DistortionPosture      = <posture token; optional note>

    Cross-space form

    SourceSetFamily      = ...
SourceSetRef?       = ...
SearchSpaceRef         = SearchCharacteristicSpace@...
OutcomeSpaceRef        = OutcomeCharacteristicSpace@...
SpaceRefRelationKind   = distinctDeclaredSpaceFrom
SourceToOutcomeRelation= <direction, mode, carrier>
DistortionPosture      = <posture token; optional note>

    If neither rewrite form can be completed honestly, the line is not yet publishable as substrate-bearing text.
